Holding furnace, is arranged on casting mold to be poured into a mould in frame, and then passing to compressed air makes molten metal enter casting by stalk
Type, through a liter liquid, stamp, crust, supercharging, pressurize, pressure release, cooling.Complete an operating process.
Existing magnesium alloy low-pressure die-casting machine is come by the transformation of aluminum alloy low-pressure casting machine mostly, and no Simulation Based On Multi-step is protected
Shield, whole casting process are uncontrollable, are likely to occur jet phenomenon at any time, but as magnesium alloy one is ejected, in atmosphere
Vigorous combustion, or even blast, have a strong impact on personnel equipment's safety；Both the above equipment molten metal falls after the completion of needing melting simultaneously
Enter holding furnace, for magnesium alloy, in handling process easily with air contact oxidizing fire, it is dangerous very big；Therefore existing magnesium is closed
Golden air injection machine safety is not high.
